S IDE FRAME Filed Aug. 20, 1930 Wei,

Patented Oct. 2), 1936 SIDE Robert B. Cottrell, Chic FRAME ago, Ill., assigner to American Steel Foundries, Chicago, Ill., a corpora- This invention pertains to side frames.

It is an object of this invention to provide a truck side frame so designed as to meet all test requirements for A. R. A. side frames of this type.

' VA further object of the invention is to provide aV Vulcan side frame adapted for use with the suitable journal box heretofore used or any suitable journal box, yet one which fulfills all test l0. requirements of deilection and set.

Another object of the invention is to provide a side frame construction of the Vulcan type which fulfills all requirements of manufacture and service.

l5- With these and various other objects in view, the invention may consist of certain novel features of construction and operation as will be more fully described and particularly pointed out in the speciiication, drawing and claims appended hereto.

In the drawing, which illustrates an embodiment of the device and wherein like reference characters are used to designate like parts- Figure 1 is a top plan view of substantially one-half of a Vulcan type side frame embodying the invention;

Figure 2 is a side elevation of the side frame construction illustrated in Figure l;

Figure 3 is a bottom plan View of the side frame 30. construction illustrated in Figure 1; and

Figure 4 is an end elevation of the side frame construction illustrated in Figure 1.

The side frame construction is shown as of the so-called Vulcan type and includes a tension 35. member Ill, a. compression member l2 merging adjacent the ends thereof into an end portion I4 disposed above the integral spaced jaws I6 adapted to receive the suitable journal box associated With this construction, a securing lug I8 v being provided between said jaws for receiving a securing bolt or other fastening means for said journal box. The tension member includes the spring seat portion 20 and the upwardly extending portion 22, said portion merging with the downwardly extending portion 2t of the compression member i2, said portion 2li merging into the end portion ifi and into a central portion 26, the tension and compression members iii and l2 being integrally connected by means of the spaced 5o column guides 28.

`'I'he portions 22 and 2t of each of the tension and compression members are substantially U-shaped in section and face each other in way of the reinforcing flange 30 integrally formed 55; with the tension and compression member and 1930, Serial No. 476,460

(Cl. 10E- 205) each of the column guides. The central portion 25 of the compression member between the spaced column guides is substantially parallel sided, the portion Z2 converging toward the end portion IE., the member 2t being of substantially greater transverse cross-section than the cross section of the member 22 as indicated in Figure 4. The end portion ifi comprises the upper and lower parts 32 and 38 which are formed with the spaced walls 34 and 37, respectively, connected together by the walls 35 which converge downwardly from walls Shi toward each other over the jaws IE to merge with the Walls 3i'. It will be noticed that the parts 32 and 38 are formed as substantially continuations of the compression and tension members, respectively. The walls 3i of low-er part 3S are spaced apart substantially the same distance as the walls of the tension member 22 and are connected by a web 39 which is a Continuation of web d thereof. The upper part 32 has side walls 34 connected by a top web il formed as a continuation of the web of the compression member 2li and these walls to a point 43 are spaced apart at substantially the same distance as the walls of this compression member. From the point i3 outwardly to the end of this part the walls 34 converge toward each other.

Cross ribs iii and 42 are provided in the member 24 of the compression member adjacent the end of the aperture formed by the side portions which form a brace for the side walls, preventing collapse of these side walls which in eiect are Warped, and it will be noticed that the bottom or connecting wall of the member 22 is increased in thickness toward the upper portion thereof as at d4 to provide increased strength adjacent the inner corner of the journal box adjacent the inner of the jaws l5.

With this construction it will be seen that a very advantageous, rigid and strong construction is provided and it is to be understood that I do not wish to be limited by the exact embodiment of the device shown, which is merely by way of illustration and not limitation, as various and other forms of the device will of course be apparent to those skilled in the art Without departing from the spirit of the invention or the scope of the claims.
